Thousands of people gathering for the rally at the Kim Il Sung square. On Friday (September 9), Pyongyang set off its most powerful nuclear blast to date, saying it had mastered the ability to mount a warhead on a ballistic missile, ratcheting up a threat that its rivals and the United Nations have been powerless to contain. South Korea said on Monday (September 12) the North is ready to conduct an additional nuclear test at any time. On Tuesday, two U.S. B-1 bombers flew over South Korea in a show of force and solidarity with its ally; AFP reported.
